McCain, who has identified as a Republican in the past, could well offer the viewpoint of a different member of that political party: one hailing from the millennial generation. She has in the past championed gay rights and come out against anti-immigration legislation, and has publicly challenged commentators like Ann Coulter and Laura Ingraham. In her writings she’s expressed ambivalence about Sarah Palin, the former Fox News contributor who ran for U.S. vice president alongside her father, and admiration for Hillary Clinton, who is now vying for the Democratic nomination for U.S. president.

McCain most recently was a host for “TakePart Live,” a talk show on cable’s Pivot network that urged viewers to get involved with various social causes. She was also the focus of “Raising McCain,” a Pivot talk show that took her on the road. Both were cancelled.
